I read the twilight books, and so far have watched all of the movies. The books were easy reads, and as many have said, high school level writing. Nothing spectacular, nothing absolutely addicting. Upon watching the first movie, the acting seemed poor to me and the only scene that ever had any serious sense to it was the scene Edward removes himself from his car, saving Bella from a bunch of thugs in some back alley. At least you could get some kind of 'creepy' feel in that scene, due to Edward's expression. New moon was only fascinating to me due to the computerized wolves. I enjoy wolves in general, so that was the only portion of New moon that was worth watching. Now for Eclipse, as this article displays the scene in the mountains with the verbal fighting between Edward and Jacob, and Bella being unconscious, i think this sends a bad message. In the books, as well as in the movies, Bella is of course female and made out to be some kind of helpless klutz.
It's as though she can't make choices for herself, and Edward and Jacob are attempting to make the decision for her. Stephanie Meyer portrayed Jacob, in my opinion, as a better option for her. The cold that happens in the mountain scene shows that Jacob, with his body heat, was able to save Bella more than Edward could. Plus, in the movies and the books it is explained that the wolves hold some sort of grudge against the vampires. Or a strong dislike, therefore a treaty was made between the wolves and Cullens, and through the movies it appears other vampires. So therefore, i believe Bella would have been much safer in the hands of Jacob. But instead, she chooses Edward - the icicle, who drags her into danger.
So, i do disagree with the fact that Bella, as a girl, is portrayed as a vulnerable character. Women aren't that terribly clumsy, or helpless. Plus, Bella makes some pretty wrong choices in my opinion and i agree that Edward and Jacob should have worked better in the situation, made something work for the two of them, allowed Bella to make a decision for herself, etc.
